When the first cylinder 101 is lowered into the borehole, the support device The device is separated from the top of the first cylinder 101, and then the first cylinder 101 is fixed inside the borehole by the traveling device, and then the second cylinder 102 is pushed downward, so that the second cylinder 102 and the third cylinder 103 continue to move downward. When the second cylinder 102 moves downward to the maximum stroke, the traveling device fixes the third cylinder 103 inside the borehole. At this time, the first cylinder 101 is moved downward to the borehole, and the first cylinder 101 and the second cylinder 102 are continuously and alternately moved downward, so that the third cylinder 103 continues to move downward to the soil. When the set depth is reached, sampling is performed through the sampling device.

[0043] The main functions achieved by the present invention are: the first cylinder 101 and the second cylinder 102 are continuously and alternately moved downward, so that the third cylinder 103 is continuously moved downward into the soil, and when the set depth is reached, sampling is performed through the sampling device, thereby improving the convenience of the sampler for multi-section sampling of deeper soil, reducing the limitation of sampling by the length of the drill rod, and improving the convenience of use;

[0044] Since the third cylinder 103 forms a complete borehole in the soil with a smooth inner wall when moving downward, the mixing of soils at different depths is reduced, thereby improving the accuracy of multi-segment soil sampling.

[0045] The first oil cylinder 201, the first motor 203, the second oil cylinder 307, the third oil cylinder 403, the fourth oil cylinder 405, the clamping oil cylinder 504, the fifth oil cylinder 601, the second motor 703, the third motor 802 and the electric hoist 901 of the soil depth multi-stage sampler of the present invention are purchased on the market. The technicians in the industry only need to install and operate them according to the accompanying instruction manual, without the need for the technicians in this field to make creative efforts.

[0046] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
